*2.A.51.1.5









Chromate efflux protein Chr3N/Chr3C, or YwrB/YwrA (Díaz-Magaña et al., 2009).  Each protein has 5 TMSs, but they have antiparallel orientation in the membrane: Chr3N has the C-terminus in the cytoplasm while Chr3C has the C-terminus facing the extracellular medium (Martínez-Valencia et al. 2012).
